Title: Manual copying device
Inventor: KURATA KAZUYUKI
IPC: H04N1/107
Filed: 1986-11-05
Abstract: PURPOSE:To improve the reproducibility of an image by matching, detecting and storing the reading position data on the original image of respective image data at the time of reading the image of a constant time interval. CONSTITUTION:When a copying device main body 11 is moved so that an aper ture part 11a can face on the upper surface of an original at the time of reading the image of a constant time interval, the image data of an image surface are stored into a control part. At this time, when a roller 15 is rotated with one rotation, a roller 16 and a slit disk 16a are also rotated by one rotation and the slit of a slit disk 16a is detected by a photointerrupter 17. Thus, every time the copying device main body 11 is moved by a prescribed quantity, the photointerrupter 17 detects the slit and the image position is simultaneously detected. Thus, the reproducibility is improved.

Title: Device for cooling electronic component
Inventor: UIRIAMU DEERU KORUFUITSUTSU
IPC: H05K7/14
Filed: 1990-10-02
Abstract: PURPOSE: To provide a small, inexpensive and highly efficient device by providing a plenum chamber and an electric air shift device discharging air to a Ω-shaped passage having at least four direction changing points through from the lower member of a back storage room to the upper member of the back storage room. CONSTITUTION: Preheated air flows upward through a member 55, a book 11 and a member 51 by using the Ω-shaped passage. A radius 58 changes again the direction of air at the position 75, and it discharges air in a horizontal direction as shown by 76 through the back of an enclosure 20. Since the direction of the air passage is converted four times, the air shift device 60 allow the air flow to change its direction once and the other three changes can be made by a direction changing blade without increasing the upper space. Since the plenum chamber 27 for reducing the impedance uses height which the air shift device 60 previously requires, more space is not required. Thus, a highly efficient electronic part cooling device can inexpensively be provided.

Filed: 1994-10-04
Abstract: PURPOSE: To stabilize a control system without degrading responsibility even though a battery voltage has been fluctuated by setting a control gain for input and output systems based on a detected voltage value of voltage detecting means. CONSTITUTION: A battery voltage detected by a battery voltage detecting circuit 66 and a microcomputer 21 is read through an A/D converter 27, and a PWM gain corresponding to the battery voltage is set by, for example, multiplying a predetermined proportional coefficient by the battery voltage.

Abstract: PURPOSE:To optionally set step interval by providing a counter to set up pullback times on the basis of signals from a pullback distance sensor, an electromagnetic valve means to stop feeding and advancing on the basis of pullback times, and a pullback time setter. CONSTITUTION:During the vertical moving period of a drill rod 3, the pullback distance of a feed chain engaged with a sprocket 2 is obtained by the rotary encoder 4 of a step pullback device 1. Detected signal 100 proportional to pullback moving distance from the encoder 4 by a counter 5 is compared with a preset value.

In the valve 6, the pullback of the drill head 3 is stopped. Furthermore, in a pullback timer 7, when the set time is timed up, the stop action of the valve 6 is released to repeat step pullback action again.

The coating material 7 is thus splashed in the form of a mist from the coating material sucking-up and absorbing material 4.  The adjustment of the amt. of the coating material 7 to be sprayed is executed by turning the coating material spraying amt. adjusting screw 5 to vertically move the screw and adjusting the amt. of the coating material 7 to be sprayed by changing the position of the air nozzle 3. The vessel is hermetically closed by the cap 8 for preventing drying in order to prevent the drying of the coating material sucking-up and absorbing material 4 after use.

IPC: G11B5/842
Filed: 1988-10-20
Abstract: PURPOSE:To obtain excellent traveling durability under various environmental conditions and little elevation of initial driving torque by incorporating three- dimensional crosslink structures produced by crosslinking reaction of polyisocyanate having three functional groups into a magnetic layer and specifying the number of crosslinkages. CONSTITUTION:The magnetic layer contains three-dimensional crosslink structures produced by crosslinking reaction of polyisocyanate having three functional groups, and the number of crosslinkages is specified to 1X10<20> - 5X10<20> per 1 gram of a binder resin. The three-dimensional crosslink structures are produced by crosslinking reaction of polyisocyanate itself or polyisocyanate and the binder resin such as polyurethane having -OH groups in its molecule. As the number of crosslinkages produced is >=1X10<20> per 1 gram of the binder resin, the magnetic layer has high film strength. However, the coating film of the magnetic layer does not become brittle because the number of crroslinkages is specified to <=5X10<20>.

Filed: 1985-11-26
Abstract: PURPOSE:To enhance the accuracy of impedance matching a adjustment by setting the relationship in the winding direction between first and second coils so that respective current phases may be reverse to each other. CONSTITUTION:A first coil 24 and a second coil 26, first and second arbitrary taps, are connected with each other by a capacitor 25. Part of a current Ii flowing through the first coil 24 driven by a signal source 23 flows as a current Ic into the second coil 26 through the coupling capacitor 25.
